To (all whom it In/nay concern:

Be it known that I, OGTAVE A. Pornrnn, 0t

Gladstone, county of Ramsey, State of Min nesotn, have invented certain. new and useful. Improvements in Bearings for Dist: Drills, of which the following is a. specification. H The object of my inventionis to provide a. bearing for single-disk drills which will he of simple and economical construction and preetically dust-proof.

A further object is to provide means for keeping the surfaces of the disk free from mild enddirt.

Other objects of the invention will appear from the'i'ollowing detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described. and peiticulsrly pointed out in the claims.

In the accompanying drawings, forming pert of this specification, Figure 1 is a side elevation of s disk and boot embodying my invention.

the single type having a centrally-arranged,

hole 3, over which a cup 4, having an inteteriorly arranged ,runwnyfi, is secured. A series of balls 6 are arranged in said runway, and a n1oveblecone-benring 7 is provided between seid balls and the drill-disk and has an extension 8 on one side projecting through the hole 3 and provided with 1 socket 9, that is square in cross-section and adapted to receive a similarly-shaped lie'ygbymcens of which said cone 'iis revolved. The other side or'the cone 7 is provided with a threaded stud 10, that fits in a threaded opening in it fixed cone-bearing 11, that is provided on the inside or" a. cap 12, arranged to cover the cup rind conceel the same. The end of the stud .10 pro- Fig. 2- is a top view of the'serne. Fig. 3 1s a VBliJlCEil section on the line 3/ y, of

opening 14% preferably provided intc upper portion of the cap 12, tl'irongh which it sup o ply of oil may he delivered to the bell-d lhc cap .12 is preferably formed into with the drill-brat .15, that is i the usual groin-spout cont 7 12 by n curvci (a, i, Pg. 52, is some little dis face of the disk to allow rind up by the dish to fell dcr. At the lower portion of the provide on extension 17 or hnring n longitudinellywir edge 19, adapted .to keep the of mud and dirt that nccunnii and at the upper end of the ed; a. similar edge 20, forming an ext-c edge 19, but oppositely inclined. to con to the change in direction of travel or disk. In front of the cap 12 is an arm 2.1.; h e ing a. cleaning edge 22, that adopted to h on the surface of the disk on its down sine and clean off any accumulation oi. dirt that may have escaped the cleaning edges on the up side of the disk. -The disk dragdmr not shown in the drawings) is connectco to the arm 21 by bolts or other suitable means.

The manner of using my improved single.

disk drill is as follows: The cup 4 linvingbccn secured on the surface of the disk, the mor able cone 7 is placed therein and tlfe disk mounted on the boot. By means of the socket in the end of the extension 8 the operator can readily adjustthe movnbie cone so that the disk will turn withproper freedom in its hearing, and when the proper adjustment has been made the movable cone is locked by means of the lock-nut 13, and the device is ready for use. The cleaningedges on the boot will keep the surface of the disk free from mud and dirt, so that its edge will be clean and bright to, enter the soil the desired depth. I claim asmy-invention 1. The combinetionnwith a drill-disk, of a cap secured thereon and having a fixed cone,

&

. a movable cone interposed between said fixed witha socket projecting through said hole, a'

threaded stud provided on the other side of ,said cone, :1 cap having a threaded hole to receive said stud, a lock-nut for said stud, and

' bearing-balls interposed between said cones.

4, The combination, with a drill-disk, of a cap fitting the convex surface thereof, fixed and movable cones, a runway secured to said disk, and hearing-balls arranged in said runway between said cones.

A hearing for a single-disk drill comprising a ball-runway secured to the surface of the disk, a movable cone adjustably arranged in said runway, a boot provided with a=cap covering said cone and runway, a fixed cone provided on said cap, and bearing-balls interposed between said cones.

5. The combination, withadrill-disk having a central opening, of a cup having a ball-runway secured over said. opening, a movable cone arranged in said cup and having an extension provided with a squared socket projecting through said opening, a threaded stud provided on the other side of said cone, aboot havinga cap covering said cone and runway, a fixed cone carried by said cap and having a threaded hole to receive said stud, a ioek-nut provided on said stud, and bearing-balls arranged in said runway between said cones.

7. The combination, with a driil-diskof a boot having a depending extension, and cleaner edges provided on said extension and arranged to bear upon the surface of said disk.

8. The combination, with a drill-disk, of a boot having oppositely-inclined cleaner edges substantially in line with each other- 9. The combination, with a drili-disl.-:-, of a boothavingalongitudinally-arranged cleaning gdg; adapted to bear upon the surface of said 10. The combination, with a disk drill and. its bearing, of a cap concealing said hearing, a drill-boot, and an outwardly-curved wall connecting said boot and cap, for the purpose specified.

11. Thecombination, with a drill-boot and an integral cap thereon, a drill-disk, a bailbearing therefor interposed between said disk and cap and covered by the latter, substantially as described.

12. The combination, with a drill-boot and a cap formed integral therewith,- of a drill-disk, a ball bearing therefor interposed between said disk and cap and concealed by the latter, and cleaning edges provided on said boot and arranged to clean the up'and down sides of said disk.

In witness whereof I have hereunto set my hand this 7th day of September, 1903.
